Update: The Denver District Attorney's Office has formally charged Jamie Valdiviezo-Perez, 39, and a juvenile (presumably his son) in the murder of a man whose body was found in a South Quieto Way alley. As sketched out by the arrest affidavit on view below, police were led to the alleged shooters by a couple of unusual clues -- a pair of red Pumas and a blanket with a tiger on it.

As you'll see, the names of many folks who spoke to police have been removed from the affidavit, likely due either to age (in the case of the juvenile suspect) or status as witnesses against Valdiviezo-Perera. The victim has been identified as Juan Hernandez-Soto, but In the document, he's referred to by his nickname: El Cholo.

Early on Saturday the 16th, according to the report, police received a call about a Hispanic male found wrapped in a blanket. The man had been shot in the face, stomach and left arm. He was wearing a white tank top, blue jeans and red-and-white Pumas, while the blanket sported a black-and-white tiger -- details that would prove important before long.

Why? Detectives on the scene soon discovered that police had received another call from the neighborhood at about 3:13 a.m. The unnamed men at the apartment in question, on South Quivas Street, about three blocks south and two blocks west of where the body was discovered, told officers that they'd been out, and when they returned, they found blood and spent shell casings in the living room. Moreover, their roommate, a short, skinny Hispanic in his mid-twenties (he was actually 27) known to them only as El Cholo, was missing.

The basic description of El Cholo matched that of the man found in the alley, right down to the red Pumas and a blanket he owned -- one with a black-and-white animal on it. Detectives promptly obtained a search warrant for the South Quivas pad.

Then, later that evening, officers received a call from someone who had information about the crime -- details that prompted an interview with the tipster and a second individual, as well as the following story.

The two said the suspect, who they called Jamie, had visited the El Sinaloense, a bar not far from the South Quivas apartment. (His son was present, too, but because of his age, he waited for his father in his truck.) The drinking continued back at the South Quivas apartment, but at some point, the witnesses went to bed.

Some time later, El Cholo got up to use the bathroom, and when he returned to the living room, one of the witnesses heard a gunshot. "There, there, Jamie, you got me," El Cholo said -- after which three or more shots were fired.

Afterward, Jamie, who was seen with a black gun in his hand, asked for plastic bags and a blanket from the bedroom -- the one with the tiger on it. The witnesses are said to have reacted by distancing themselves from the situation, saying that whatever went down was between Jamie and El Cholo. They left it to Jamie to wrap up the body, dump him in the back of his truck, and drive him away...although not too far.

Before long, detectives discovered that Jamie was Valdiviezo-Perera, and after his picture was selected from photo lineups, he was busted on suspicion of first-degree murder. To that accusation, the Denver DA's office added two charges of menacing, for attempting to goad the witnesses at the apartment into helping him dispose of El Cholo's body. Valdiviezo-Perera is scheduled for a court appearance at 1:30 p.m. today to be formally advised of the counts against him.

Update, 7:01 a.m. June 22: The man whose bullet-pierced body was found in a South Quieto alley this past weekend still has not been identified by the Denver coroner's office.

However, we now know the moniker of one man the Denver Police believe is responsible for his death: Jamie Valdiviezo-Perera, age 39. His alleged co-conspirator? An unnamed juvenile.

As we reported earlier this week, the DPD hasn't shared much information beyond the barest of basics. Officers received a call at 6:11 a.m. on Saturday about a cadaver located in the 1200 block alley of South Quieto Way and South Raritan Street. The victim had been shot multiple times, but apparently not where he fell. Investigators quickly came to suspect that the crime had been committed elsewhere, after which the body was dumped.

Valdiviezo-Perera's mug shot hasn't been shared at this point, and neither has anything about the juvenile arrested along with him -- not even gender. Clearly, there are a lot more gaps that need to be filled.

Look below to see our previous coverage, complete with a graphic showing the area where the body was found.

Original post, 8:58 a.m. June 18: Early Saturday morning, members of the Denver Police Department discovered a body in an alley. There was little question about whether the incident should be investigated as a homicide, given the bullets involved. But thus far, the DPD is being conservative about the release of case ino, other than to hint that the victim may have been dumped in the spot he was found, rather than being killed there.

At about 6:11 a.m. on Saturday, according to the DPD, officers responded to a call about a body found lying in the 1200 block alley of South Quieto Way and South Raritan Street. There, they discovered that the man had suffered gunshot wounds -- plural.

In addition, investigators the body may have been dumped in the alley after the crime was committed.

The Denver coroner's office is in charge of releasing the name of the victim. Meanwhile, no suspects have been named.
